Radiocarbon dating of wood
PY - 2008/12Y1 - 2008/12N2 - In the Angkor monuments of Cambodia, pieces of wood remain (as head frames of doorways, crossbeams, ceiling boards, etc.) in the following 8 monuments: Bakong, Lolei, Baksei Chamkrong, North Khleang, Angkor Wat, Banteay Kdei, Bayon, and Gates of Angkor Thom.
In order to ascertain the ages of samples which were formed in equilibrium with different reservoirs to these materials, it is necessary to provide an age correction.Radiocarbon dating is the most common technique used in ascertaining the age of archaeological and paleontological sites during the last 45,000 years.Developed by a chemist born in Colorado, there are now commercial and academic laboratories across the globe that conduct radiocarbon dating.Sample sizes of one gram or greater are required for conventional dates.
More recently, accelerator mass spectrometry (AMS) has become widely available.
Recovery of a Zea mays cob from this cave provided an opportunity to examine it for morphometric analysis of phytoliths that would provide a numeric signature that could be compared with other cobs that have been examined and will allow for comparison with cobs analyzed in the future.
